PATENT 1 JAMES W. BRYSON, OF NEW CASTLE, PENNSYLVANIA.

MACHINE FOR CLEANING, BURNISHING," OR POLISHING TIN-PLATE.

SPECIFICATION forming part of Letters Patent No. 656,089, dated August 14, 1900. Application filed May 19, 1900. Serial No. 17,270. (its model.)

To all whom it may concern.-

Be it known that 1, JAMES W. BRYsoN, a citizen of the United States, residing at New Castle, in the county of Lawrence and State of Pennsylvania, have invented new and useful Improvements in Machines for Cleaning, Burnishing, and Polishing Tin-Plate,of which the following is a specification.

My invention relates to machines for cleaning, burnishing, and polishing tin-plate; and the object of the same is to provide a machine for this purpose which will economically, expeditiously, and efficiently clean and polish tin-plate immediately after it comes from the tinni-ng-machine and while the plates are still hot.

It has been found in practice that after the plates become cold they can be but imperfectly cleaned,owingto the fact that the dirt, grease, and other particles adhere to the plate with such tenacity that an ordinary brush will not remove them. WVhen cleaned while hot, the particles do not adhere to the plate, and they may be quickly cleaned by a machine such as is hereinafter described.

Myinvention'is designed to brush the plates in a direction reverse to the direction in which they are fed into the tinning-machine, and in this way the plates are more perfectly burnished and cleaned.

I attain the objects of my invention by means of the construction shown in the accompanying drawings, in which Figure 1 is a side View of a machine embodying my invention. Fig. 2 is an end view thereof with the conveyer removed. Fig. 3 is a side view of the machine, showing the side opposite to that presented in Fig. 1. Fig. 4 is an end view of the machine, showing the opposite end from that shown in Fig. 2. Fig. 5 is a longitudinal section of the machine.

Like characters of reference designate like parts Wherever they occur in the difierent views.

In said drawings the numeral 1 designates the framework of the machine, which consists of two uprights connected by tie-rods 2. J ournaled in the uprights 1 are the brushrollers and feed-rollers, to be hereinafter referred to. A conveyor 3, consisting of a chute or trough having a series of rollers 4, journaled' in brackets at their ends, is secured to the frame and projects longitudinally therefrom. Said chute is supported upon rods 5 at the end thereof. One of the outer rollers 4 is actuated by a drive-chain 6, which passes around a sprocket-wheel 7, upon the outer end of the roller-shaft and also around a similar sprocket upon the upper feed-roller Ct. As shown in Fig. 3, the drive-chain 6 engages a sprocket-wheel on the ends of each of the rollers 4E. The brush-rollers 7 consist of a wooden roller covered with sheepskin tanned with the W001 on. A brush of this character has been found particularly eflicient for this class of work. However, I may use brushes of different materials and structure. The

;two upper brush-rollers 7 are substantially the plates drop upon an inclined chute or trough 8, from which they slide by gravity down to a point between the two lower fric tion-rollers a to the lower brush-rollers 7 The rubber-faced friction-rollers a revolve at a speed somewhat slower than the speed of the brush-rollers, the result of which is that the brushing operation is carried on in an economical and eflicient manner. From the lower brush-rollers the plates are fed serially into an inclined trough 9, from which they fall upon an endless carrier 10, composed of a plurality of belts 11, which pass around the pulleys 12, secured to shafts 13, journaled in the framework of the machine. A belttightener 14 of ordinary construction may be used for keeping the belt in proper working condition. The troughs or chutes 8 and 9 are properly supported and braced from the frame of the machine. The feed-rollers may be provided with frictional surfaces to retard the plates against the action of the brushrollers.

As shown in Fig. 3, the brush-rollers and feed-rollers are actuated by a belt 15, passing around the pulley 16 upon the driving-shaft and back and forth upon pulleys 17 upon the ends of the feed and brush shafts. A drivechain 18 (shown in Fig. 1) passes around the sprocket-wheels 19, 20, 21, and 22 to drive one friction-roller of each pair slower than the brush-rollers. The shaft 13 is driven by a sprocket-chain b, passing around sprocket wheels 7) b Figs. 2 and 4:.

The operation -of my machine is as follows: The tin plates as they come from the tinningmachine fall upon the conveyer-rollers and pass forward between the friction feed-rollers aand on between the upper pair of brushrollers 7, the friction rollers holding the plates back to give a more perfect brushing operation. As the plates fall from the upper brush-rollers into the chute 8 they slide between the lower feed-rollers and are fed forward between the lower brush-rollers and up into the chute 9, from which they fall by gravity upon the belts 11, which convey them in a comparatively-cool state to the trucks which carry them to the assorting-room.

From the foregoing it will be obvious that a machine made in accordance with my invention will expeditiously clean and polish the tin plates while hot and perform this operation more efficiently than has been here- Having thus fully described my invention, what I claim is In a machine for cleaning tin-plate, a conveyer, comprising a plurality of rollers journaled in a chute and provided with means for revolving them, a pair of feed-rollers at the inner end of the chute, a pair of brush-rollers journaled at one side of the feed-rollers, an inclined chute below said brush-rollers, another pair of feed-rollers at the inner end of said inclined chute, a pair of brush-rollers opposite said last-mentioned feed-rollers, an inclined chute suspended from the conveyerchnte,and a conveyer-belt below said lower feed-rollers, and means for revolving said feed-rollers, brush-rollers and conveyer-belt, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
